The purpose of this study was to investigate the relationship among health locus of control, self efficacy, and demographic factors in patients with type-II diabetes mellitus. Method: Data were collected using cross-sectional, correaltional design from 793 patients with type-II diabetes in regards to health locus of control (HLOC) self-efficacy, and biomarkers. Results: The mean score for the internal subscale of HLOC was 27.2 (SD = 6.32), for the powerful others subscale of HLOC it was 30.9 (SD = 5.7), and for chance subscale of HLOC it was 18.6 (SD = 6.8). The mean total score of locus of control scale was 76.8 (SD = 13.1) ranging from 19 to 132. The mean score of HbA1C was 7.5 (SD = 2.6). Patients had moderate to high perception of powerful other health locus of control, and self efficacy. Results also showed that locus of control had positive and significant correlation with self efficacy (r = 0.18, p > 0.01) and negative relationship with HbA1C (r = -0.11, p > 0.01). On the other hand, age has no significant correlation with health locus of control. Conclusion: Health care professionals need to enhance patient’s self-efficacy and internal power of their patients for better health outcomes. Nurses and other health professionals need to emphasize the psychosocial health aspects of patients with chronic illnesses, and in particular, those diagnosed with type-II diabetes mellitus.展开更多

The aim of our study was to develop a Japanese version of the Parent Health Locus of Control (JPHLOC) Scales and to verify its validity and reliability. The JPHLOC scales consist of six scales: Professional Influence, Parental Influence, Child Influence, Media Influence, Fate Influence, and God, Buddha, and the Spirits Influence. Our questionnaire was administered to 231 principal caregivers from Japan whose children were under 6 years of age. The items, related to the “God, Buddha, and the Spirits Influence” scale, showed a floor effect. The exploratory factor analysis indicated that JPHLOC’ six factors functioned similarly to the PHLOC’ factors. The Fate Influence and Child Influence factor structures in JPHLOC scales were different from the corresponding factor structures in the original PHLOC scales in the functioning of only one item. There were statistically significant correlations between JPHLOC scales and Japanese version of the Parenting Stress Index-Short Form (PSI-SF), which add evidence to the criterion-related validity of JPHLOC scales. Furthermore, applying the known-groups method, our study showed that there was a significant difference across the JPHLOC scale scores, owning to differences in the children’s and caregivers’ demographics, which provides an evidence for construct validity. The Cronbach’s alpha coefficients for the six scales were estimated between 0.73 and 0.93. In a test-retest study, the interclass correlation coefficients for the six scales were ranged between 0.80 and 0.90. The results suggested that the JPHLOC scales have sufficient reliability and validity. The JPHLOC scales are applicable to the caregivers of healthy children. We confirm that the PHLOC scales are also applicable to Japanese caregivers.展开更多

To go to where we want to go, we must first assess where we are now. The study investigated the level of sustainability consciousness of students in India, and sustainability consciousness was expressed in sustainability knowledge, attitude, and behaviour. Sustainability consciousness was further examined using the three dimensions, such as environment, society, and economy. By drawing the perception map of students and studying the role of the locus of control, the reasons why sustainability knowledge does not appear in sustainability behaviour were analyzed. Quantitative analysis was conducted for a sample of 205 students from higher educational institutions across central India(Madhya Pradesh) from January to March in 2022. The data were analyzed using the SPSS 26 and Smart Partial Least Square(PLS) 3.0. The research revealed that sustainability attitude impacts sustainability behaviour more than sustainability knowledge. The results showed that respondents’ sustainability knowledge is higher than their sustainability attitude and behaviour. Moreover, it was discovered that economic concerns can lead to sustainability behaviour. In order to study respondents’ behaviour regarding sustainability consciousness, the study divided respondents into two groups according to the locus of control: the internal and external locus of control. It was found that most respondents thought whatever happened around them was beyond their control. Further, the locus of control influenced sustainability behaviour in groups with the internal locus of control. The study helps to explain why sustainability knowledge and attitude cannot translate into sustainability behaviour and provides a basis for achieving sustainable development. The conclusions of this study are crucial for governments, educational institutions, and organizations that empower youth to change their behaviour.展开更多

Some students have been observed to achieve higher while some achieve lower even after being exposed to the same subject matter by the same instructor. The objective of the study was to determine if locus of control correlated with academic achievement of students as moderated by gender and school-type. The study was anchored on attribution theory. The study adopted a correlational research design. A total of 388 SS3 students in Aba Education zone were selected using purposive and simple random sampling techniques. Instruments for data collection were an adopted LOC scale and students’ exam scores in Mathematics, English and CRS. To determine the reliability of the instrument, Kuder-Richardson reliability test (KR-20) was employed and an overall coefficient of 0.76 was obtained for LOC scale. Data were analyzed using Pearson Product Moment Correlation Coefficient. Results showed significant relationship between locus of control and academic achievement of male students.

Our objective was to collect data on genotype and phenotype for 60 leaf samples at four developmental stages, from three plant architectural positions and for three cultivars that were grown in two locations. Association mapping was conducted to detect genetic variants at quantitative trait SNP(QTS) loci, quantitative trait transcript(QTT) differences,quantitative trait protein(QTP) variability, and quantitative trait metabolite(QTM) changes,which can be summarized as QTX locus variation. The total heritabilities of the four-omics loci for both traits tested were 23.60% for epistasis and 15.26% for treatment interaction.Epistasis and environment × treatment interaction had important impacts on complex traits at all-omics levels. For decreasing chromium content and increasing total sugar in tobacco leaf, six methylated loci can be directly used for marker-assisted selection, and expression of ten QTTs, seven QTPs and six QTMs can be modified by selection or cultivation.展开更多

The design of an automatic control system that is robust against disturbance of inlet wastewater flow rate and has short process settling times is a challenging matter. The proposed control method is an I-P modi fied controller automatic control system with state variable feedback and control canonical form simulation diagram for the process. A more stable response is achieved with this type of modern control. Settling times of 0.48 days are achieved for the concentration of microorganisms,(reference value step increase of 50 mg·L-1) and 0.01 days for the concentration of oxygen(reference value step increase of 0.1 mg·L-1). Fluctuations of concentrations of oxygen and microorganisms after an inlet disturbance of5 × 103m3·d-1are small. Changes in the reference values of oxygen and microorganisms(increases by 10%, 20% and 30%) show satisfactory response of the system in all cases. Changes in the value of inlet wastewater flow rate disturbance(increases by 10%, 25%, 50% and 100%) are stabilized by the control system in short time. Maximum percent overshoot is also taken in consideration in all cases and the largest value is 25% which is acceptable. The proposed method with I-P controller is better for disturbance rejection and process settling times compared to the same method using PI controller. This method can substitute optimal control systems in ASP.展开更多

The magnitude is represented in decibels and the phase is represented by colors. It also presents how to use it to calculate different kinds of controllers. An important characteristic of this diagram is that permits to read the phase and the gain margins directly and the imaginary axis cut represents the Bode diagram. It is also possible to put the grid with damping ratio ξ and frequency ωn.展开更多

The proposed control method is an I-P modi fied controller automatic control system with state variable feedback and control canonical form simulation diagram for the process. A more stable response is achieved with this type of modern control. Settling times of 0.48 days are achieved for the concentration of microorganisms,(reference value step increase of 50 mg·L-1) and 0.01 days for the concentration of oxygen(reference value step increase of 0.1 mg·L-1). Fluctuations of concentrations of oxygen and microorganisms after an inlet disturbance of5 × 103m3·d-1are small. Changes in the reference values of oxygen and microorganisms(increases by 10%, 20% and 30%) show satisfactory response of the system in all cases. Changes in the value of inlet wastewater flow rate disturbance(increases by 10%, 25%, 50% and 100%) are stabilized by the control system in short time. Maximum percent overshoot is also taken in consideration in all cases and the largest value is 25% which is acceptable. The proposed method with I-P controller is better for disturbance rejection and process settling times compared to the same method using PI controller. This method can substitute optimal control systems in ASP.
文摘This paper presents an enhanced Root Locus diagram that consists of the representation of the phase and the magnitude of the transfer function G（s） of a system. The magnitude is represented in decibels and the phase is represented by colors. It also presents how to use it to calculate different kinds of controllers. An important characteristic of this diagram is that permits to read the phase and the gain margins directly and the imaginary axis cut represents the Bode diagram. It is also possible to put the grid with damping ratio ξ and frequency ωn.
